w. CAMERON,

applicati@ mea'setemberis, laas; serial'm. ssassa My invention relates to air :deiiectors of the type employed to deflect air current away from the window openings of an automobile stitutes the most dlscomforting condition incident to automobile travel as well as a dan- V y ger to health.

It is the purpose of my present invention to provide an air deiector which, wlen ap- Y lied, may be adjusted to a positionto efectively prevent the entrance of .air currents from any direction into the body through its related window opening and also to po sitions to deflect the air current into the body and to render the dellector inoperative or neutral. i

My invention further contemplates the provision of a deector of the type specified which, when adjusted to exclude air cur- -rents froml the bod will render proper heating possible wit out sacrificev of ventilation.

My invention also contemplates the pro'-,

vision of an air deilector which can be readily and easily operated to any desired adjustment byv an occupant within the car and which will be comparatively simple and durable in construction.

I willdescribe my mvention inthe best dand between the rear end of the openlng 11 form known to me at present and as applie to a door window of an automobile body but it will be apparent that the same issus ceptible to other a changes in form an proportions and desirable mechanical additions with the exercise of only ordinary mechanical skillA and withthe bracket 4: out departing from the spiritvthereof.

' In the invention the scope Vwhereof is set forth in the appended claims. Y Figure 5 ment'of Aan automobile body showing my 1nvention operatively associated therewith elements adjusted so as to deflect Ya'ircurrents away from its re-l lated'wndow opening;

The pivotal connections o the plate 13 with the brackets 12 are each provided by a metal 12. 'Mounted on the door 10 above and below the door window near the front end ofV v.the opening 11 are vetically alined brackets -12 and between the mount a4 front delector ment between its related ear 15 and brac et or WASHINGTON, nrs'rmcr or commu., AssIGNon 'ro Louisa or wnsnmc'ron. msrarc'r or commu y a Filgure'h and K i t 4 4 i2gure 6, a section on the line 6-6 of Figure v wing nut 17 on the bolt 16 and the brackets 12 are vertically alined vThe pivotal connectionsof the plate 19 with the brackets 18 is structurally identical with l the pivotal connections of the plates 13 with 12 as heretofore described and deflector plate 19.

each embodies a marginal clamp 20, ear 21 l a pivot bolt 22 conintegral with the clamp,

and a wing nut 23 on'said pivot-bolt.

Af horizontal deflector plate 24 is pivotally connected to the upper mar horizontal deect'or plate 2 v nected to the lower marginal 20 at 2 8 and 29 respectively.- lhe 'mounting' necting the earl 21 with its lrelated bracket 18,

ginal clamps 14 v positioned to 'deect air current fromY the opeg 11 as shown in Figures 1 andv 3, the

inner edges et the plas 2t and 27 willsbe in engagement with the outer face of the door l@ and'in'such position they serve to ellectively block vor battle upward and downward air 3@ currents which would otherwise ass through the opening 11. llt will be note that the de- `doctors 24: and 27 by engaging the door 10 serve to positively determine an angular adjustment ci the vertical detlectors. l have discovered that a thirty-,dire degree adjustment of the rerticaldciiectors from their neutrol position shown in dot and dash lines in Figure 3 is most etlicient and such adjustment is shown in full lines in Figures 1 and 3. 'llt will be noted that when the dellector 13 is in the operative position shown in Figures 1 and there would ordinarily occur a space between the body l and the vertical edge of the dellector. 'lo close this space against passage of air current therethrough ll mount on said vemical edge ol the delector a rubberv Hap which ernds across said space and engages the body A as clearly shown in Figure 5.,

To provide `for the adjustment of the deilectors by an occupant of the body A l: mount on said body above and below the window opening 1l re ectively and between the de- 'ilectors 13 an 19 brackets 31 and 32, said rbraclrets extending beneath the horizontal dedectors 2d and 2i res ectively as clearly shown in Figure 1. ln t e bracket 31 li provide a slot 33 having a curvature corresponding to the movement of the deilector 2t during adjustment of the latter. Fixed to the deiiector 2d is a pin 3d which entends through the slot 33 and carries at its free end a rotatable gripping head 35. Likewise, l' provide in the braclret 32 a slot 36 having a curvature corres ending to the movement of the dodectcr a during adjustment ot the latter. Fired on the dedector 27 isa pin 37 one end oi which extends downwardl through the E@ slot 36, while the other end t erect is positioned above the dedector 27 and has mounted thereon a rotatable gripping head 38. lt

wild be apparent that an occupant within the hody A can simultaneously graspv the gripping heads 35 and 38 and directly move ythe horizontal dedectors 2t and 27 as desired, which movement of the horizontal dedectors will of course edect angular adjustment of the vertical dedectors 13 and 19. The in and slot connections previously descriged serve to control and guide the movements of the horizontal dedectors and materially assist in their adjustment by an occupant oiA the body A. The spacement of the delectors 13 and 19 'with respect to each other and with respect to the ope 11 is such that air maracas current dedected by the dedector 13 will engage and be again deected outwardly before it can pass through the oening ll.,

llt will be noted that in; angular range of adjustment of dedectors 13 and 19 is sucient to allow said dedcctors to be positioned as shown in Figure a so as to deect air through the opening 11.
